HEATING-STOVE.

Specification of Letters 1atent.

Patented Apr. 6, H915.

Application filed November 25, 1914. Serial No. 874,015.

To all whom it may concern:

Be it known that I, HENRY B. HEMPHILL, a citizen of the United States, residing at llldorado, in the county of Saline and State of Illinois, have invented certain new and useful Improvements in Heating-Stoves, of which the following is a specification, referencev being had to the accompanying drawings.

This invention relates to certain improvements in heating stoves, and an object of the invention is to rovide a device of this general character liaving novel and improved means whereby a maximum of efficiency is attained.

Furthermore, it is an ob ect of the invention to provide a novel and improved device of this general character including hot air discharging member provided with means whereb the approximate amount of discharge may be readily observed.

The invention consists in the details of construction and in the combination and arrangement of the several. parts of my improved heating stove whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will lre carefully defined in the appended claims.

in order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a vertical sectional view taken through a stove constructed in accordance -\\ith an embodiment of my invention; Fig.

'2 is a sectional view taken substantially on the line 2--2 of Fig. 1; and Fig; 3 is a fragmentary elevational view of the upper portion of the stove'as herein set forth and illustrating certain features of the invent-ion.

As disclosed in the accompanying drawings. 1 denotes the base maintained in predetermined spaced relation above the supporting surface through the medium of the legs 2. (lpelatively supported by the base 1 is the casing or barrel 3 of the stove having mounted therein the fire pot 4, the upper extremity whereof being tapered and in communication with the smoke flue 5 lead ing through the top 6 of the casing or barrel 5-; and through which the products of combustion are adapted to be discharged. and

said flue 5 is under control of a conventional damper 7 in a manner which is believed to be self-evident.

Coacting with the fire pot 4 isa grate 8 adapted to discharge within the ash-pit 9 and it is to be observed that the ash-pit 9 and the fire pot 1 are substantially entirely spaced from the walls of the casing '3 in order to afford a surrounding air space. The fire pot 4, however, is in communication with the door opening 10 through the medium of the chute 11 whereby the requisite fuel may be properly delivered within the fire box. Coacting with the opening 10 is a conventional door 12. The ashpit 9 has in communication therewith the door opening 14 adapted to be closed by a conventional door 15 provided with a suitable air valve a for controlling the draft through the fire pot and the casing or barrel 3 is provided at a point above and adjacent to the opening 14 with an opening 16 to afford access to the grate operating member 17, said opening 16 being under control of a conventional door 18. By this arrangement, it will be readily perceived that when 'required the grate 8 may be properly agitated under the influence of the operating member 17 without interfering with the draft of the stove.

The base member 1 is provided with suitable perforations 19 to permitentry within the casing or barrel 3 of the air to be heated and.- as herein embodied, such heated air is adapted to be discharged through the members 20, herein disclosed as two in number and in communication w th the interior of the casing or barrel 1 through the top 6 thereof and having interposed therein conventional dampers 21 for controlling the flow therethrough. The upper extremity of each of the members 20 terminates in the angular-1y disposed funnel 212 herein set forth as occupying a substantially horizontal plane and rotatably mounted within such funnel is a fan member 23 adapted to be rotated under the influence of the heated air discharged through the funnel and. as is believed to be self-evident, the speed of rotation of the fan will readily indicate to an observer the approximate amount of hot air being delivered within the room to be heated.

it is also desirable when required to make my improved stove a base heater. and for this purpose I have in coumiunimtion as at b. with the upper portion of the ash-nit 9.

the flue 24, herein disclosed as comprising a laterally curved sheet of metal suitably secured to the Wall of the casing or barrel 3 and disposed vertically thereof and terminating a predetermined distance below the top 6 and with the upper end of the flue 24 open whereby it Will be perceived that upon closing the dampers 21 and the valve a in the door 15, the heated air will be directed downwardly, as is believed to be clearly apparent to those skilled in the art to which my present invention appertains.

It is to be observed that the pipe or flue 24 is of a comparatively small diameter and that when the dampers 21 are open the major portion of the air admitted Within the casing 3 through the openings 19 will pass out through the members 20. It is also to be observed that with a stove constructed in accordance with myinvention substantially entirely all of the heat generated is employed. It will be observed that the radiation of the heat from the ashes Within the pit 9 serves to heat the air.

From the foregoing description, it is thought to be obvious that a heating stove constructed in accordance With my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the con-' venience and facility with which it'niay be assembled, and it will. also be obvious that my invention is susceptible of some change and modification Without material departure from the principles and spirit thereof. and for this reason I do not Wish to be understood-as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A device of the character described comprising a casing, supporting means therefor maintaining the same normally spaced from its supporting surface, the base of the casing being provided with openings,

I a fire box and ash-pit supported within the casing and substantially entirely surrounded by an air space, and a flue in communication With the ash-pit and the upper portion of the casing.

2. A device-of the character described comprising a casing, supporting means therefor for maintaining the same in spaced relation above the supporting surface, the base ofthe casing being provided with openings, a fire boX and ash-pit mounted within the casing and substantially entirely surrounded by an air space, a discharge member in communication with the casing through the top thereof, a revoluble member mounted in the free end of the discharge member and adapted to rotate under the influence of the heated air-passing through said discharge member, a flue in communication with the ash-pit and the upper portion of the casing, an air valve in communication with the ash-pit, and means for controlling the flow through the discharge member.

3. A. device of the character described comprising a casing, supporting means therefor. for maintaining the same in spaced relation above the supporting surface, the base of the casing being provided with openings, a fire box, an ash-pit mounted Within the casing and substantially entirelysurrounded by an air space, a discharge member in communication With the casing through the top thereof, means for controlling the flow through the discharge member, and a flue 'in communicationwith the upper portion of the ash-pit and the upper portion of the casing, and an air valve in communication with the ash-pit.

In testimony whereof I hereunto aflixmy signature in the presence'of two witnesses.

HENRY B. HEMPHILL.
